3. Compute the fraction of the bandwidth that is wasted on overhead (headers and retransmissions) for protocol 6 on a heavily loaded 50-kbps satellite channel with

data frames consisting of 40 header and 3960 data bits. Assume that the signal

propagation time from the earth to the satellite is 270 msec. ACK frames never
